GUN-SIGHT.

Specification of Letters Patent.

Patented Aug. 28, 1917.

Application led April 24, 1916. Serial No. 93,293.

To IZ whom t may concern:

Be it known that I, CLAUDE BEAVER, a citizen of the United States, residing at Fishers, in the county of Hamilton and State of Indiana, have invented a new and useful Gun-Sight, of which the following is a specification.

It is the object of my invention to provide an adjustable gun sight, which can be adjusted for distance, for wind deflection, and for visual peculiarities of the user; and in which the adjustments can be made readily, with the gun in position to be raised, and on scales which are easily and conveniently visible.

The accompanying drawing illustrates my invention. Figure 1 is a perspective View of a gun sight embodying my invention, showing a fragment of the gun barrel on which it is mounted; Fig. 2 is an enlarged section through the outer end of the sightcarrying arm; Figs. 3 and 4 are sections on the lines 3-3 and 4-4 respectively of Fig. 2; Fig. 5 is an elevation of the outer end of the sight-carrying arm, taken from the same point of view as Fig. 2; Fig. 6 is a plan of the parts shown in Figs. 2 and 5; and Fig. 7 is an enlarged section through the spring latch controlling the distance adjustment.

Mounted on the gun barrel 10, which is of any desired character and is provided with any suitable front sight 11, is the base plate 12 of my improved rear sight, which is held to the gun barrel 10 in any manner, as by screws 13. At the forward end of this base plate 12 is hinged a sight-carrying arm 14, which projects upwardly and rearwardly therefrom at an adjustable angle. A link 15 is pivoted at its forward end to an intermediate point on the sight-carrying arm, and at its rear end to a slide 16 which overlaps the edges of the base plate 12 and is slidable forwardly and rearwardly thereon. By this sliding the angle at which the sightcarrying arm 14 stands is adjustable through about The left hand edge of the base plate 12 is provided with teeth 17 which cooperate with the down-turned end of a latch lever 18 which is pivoted on the slide 16 and has a cross arm extending over such slide and provided at its right hand end with a button 19 in convenient position to be engaged by the users right thumb. The latch lever is pressed into engagement with the teeth 17 by a suitable spring 20 acting on the under side of the cross arm. The rear edge of the slide 16 is provided with a pointer 21 which travels over a scale 22 on the base plate 12 as the slide 16 is adjusted, such scale being suitably graduated for the distance of the object aimed at. Thisscale 22 is visible with the gun in position to be raised to the shoulder, so that the distance adjustment may be obtained by merely pressing the button 19 by the right thumb and moving the slide 16 along the scale 22 until the pointer 21 indicates the proper distance.

The upper end of the sight-carrying arm 14 is provided with a transverse groove 25, in which is mounted a 'transversely moving slide 26 having a linger 27 which projects between the two bifurcations 28 with which such sight-carrying arm 14 is provided; and a screw 29 extends through such bifurcations and has a threaded engagement with the finger 27. By turning the knob 30 at the right hand end of the screw 29, the slide 26 is moved transversely of the gun barrel. The knob 30 is operable by the users right thumb and linger, with the gun either at the shoulder or in position to be raised thereto, and the slide 26 is provided with a scale 31 which by the movement of such slide travels under a pointer 32 on that side of the grooved end of the sight-carrying arm 14 which is toward the user. The scale 31 is suitably graduated to indicate corrections for wind deflection, which corrections are made by the adjustment of the slide 26.

The slide 26 is provided with a slot 35 parallel to the groove 25, and a right and left hand screw 36 operable by a knob 37, conveniently at the left, is mounted inl such slot and engages the inturned fingers 38 and 39 of two sight members 40 and 41 so as to move them toward and from each other by the turning of the screws 36. These sight members 40 and 41 are portions of cylinders fitting on the outside of the slide 26, and the member 40 has a tongue 42, cylindrical exteriorly, which underlies the member 41. The sight slot 43 is formed by the adjacent edges of the sight members 4() and 41 and the outer surface of the tongue 42, and may be adjusted in width to suit the visual peculiarities and fancies of the individual user. Because the tongue 42 is cylindrical exteriorly, its outer surface is always at the same distance from the axis of the screw 36 vfancy of the user.

regardless of the adjustment of the slide 16. The fingers 38 and 39 are enlarged at their ends, and the slot 35 is undercut, so that the sight members 40 and 41 and the screw 36 are interlocked withinl such slot; but to permit the removal of said sight members and screw when desired, the narrow upper part of the slot 35 has two cut out portions 44 transverse to the slot proper, with which cut out portions the fingers 38 and 39 may be made to register by proper manipulation of the knob 37, such registering occurring when the slot 43 is wider than it would ever be in actual use. If desired, a scale 45 may be provided on the transverse slide 26 to cooperate with indicating fingers 46 on the sight members 40 and 41; but ordinarily this scale is not necessary, as the average gun user prefers to adjust the Width of his sight slot to suit his own fancy independently of any scale.

Thus by moving the slide 16 forwardly or rearwardly the sight may be raised or lowered to adjust for distance, which is indicated on the scale 22 so that the adjustment can be made easily and with the gun in position to be raised; by turning the knob 30 the transverse slide 26 and with it the sight slot 43 may be moved to the right or left to compensate for wind deflection, the proper adjustment being indicated on the scale 31 which is visible even with the gun at the shoulder; and by turning the knob 37 the slot 43 may be adjusted to suit the The first two of these adjustments are made with the right hand, since they are the ones which would re uire to be made rather promptly. The thir adjustment is made with the left hand, since it would ordinarily not have to be changed frequently.

I claim as my invention:
